利用基于长PCR的方法对一种蜉蝣Parafronurus youi（节肢动物门：昆虫门：翼状门：蜉蝣目：七甲科）的第一个完整的线粒体基因组进行了测序。基因组是一个长15，481 bp的环状分子，编码38个基因。其中，37个基因在其他保守的昆虫线粒体基因组中发现，第38个独特的基因是trnM-like（trnM 2）。复制-随机丢失模型至少可以解释其中一种易位。对照区的A+T含量为57%，是迄今为止在六足类中检测到的最低比例。基于12个蛋白质编码基因的核苷酸数据集和相应的氨基酸数据集，贝叶斯推断和最大似然分析得到了有翅昆虫3个基本分支之间关系为蜉蝣目+（蜻蜓目+新翅目）的稳定支持。(c)2008 Elsevier B.

The first complete mitochondrial genome of a mayfly, Parafronurus youi (Arthropoda: Insecta: Pterygota: Ephemeroptera: Heptageniidae), was sequenced using a long PCR-based approach. The genome is a circular molecule of 15,481 bp in length, and encodes the set of 38 genes. Among them, 37 genes are found in other conservative insect mitochondrial genomes, and the 38(th) unique gene is trnM-like (trnM2). The duplication-random loss model can be used to explain one of the translocations at least. The A+T content of the control region is 57%, the lowest proportion detected so far in Hexapoda. Based on the nucleotide dataset and the corresponding amino acid dataset of 12 protein-coding genes, Bayesian inference and maximum likelihood analyses yielded stable support for the relationship of the three basal clades of winged insects as Ephemeroptera +(Odonata +Neoptera).
